chamber or compartment 16. The pressure regulating chamber or compartment is provided with a supply `governor comprising the valve l5, a lever 34 connected `to vthe valve and adapted to open or close the-valve, and an adjustable tension bar 17 mounted upon the topyof the regulating chambergby means oi a spring 18. vThe lever is adjusted ontlie tension bar 1T-by means of a nut The numeral 19 represents a cylinder connected tothe supply regulating chamber and provided With `a piston 20' to operate therein, said piston having the rod 21 to extend beyondthe cylinder to engage, and acting as a push rod 'fortlie'lever'/S. f 'i The numeral 22l designates ai rotor Akeyed to sliaftlf by means cfa key 23. This rotor isadaptedto rotate within the stator,

'which embodies a cylindrical casing 24, the

sides `.25 ofivhich `are providedwith annular oil `iooves 25 and said-casing is connected to thel base 10 by the ,sides 25 andfbolts126.

Mounted between "the .j stator V2li' and the pressure regulatingchamberlis a rotary disk p or valve 427 provided with suitable operating means 28 Yas clearlyshown inFig. .4 of the drawing; Thepressureregulating fcliamber 16 isprovided withadsleeve 29 extending through j the `.wall `4 far 'enough tgo provide' a seatlor the rotary valve. 27. .The

` rotary valve` 'has a. series ofports adapted ytoregister ywith similar ports 31 inntliepres`- sure regulating chamber 16 land ports32`fin the stator casingQl.

`The drivingiiuid .isy `admitted *through these'ports into poclets'inf the; rotor. lllie pockets 33 are adjacent to and communicate with slots 36, said slots beingadapteol to receive sliding vanesor pistons S7'. Each ,sliding vane orpiston is provided withi a longitudinalrecess 3,81 as is l clearly shoivii` in .,Fig, 9 lof 4tliedrawings.V VThe"drivingpressure' `passes through the recessfSin theend Aofthe slot thereby'jstrilringltheends of kthel sliding varies orjpi'stons 37 and forcing the same out. .Each 'vane or Pisten-is' Prthe side edges of each slidingvane or eled end 39 for-the reception of a lubricant. Longitudinal grooves 4l() arefornied in the tor haust ports 44 to register with similar ports in the rotor casing. Y. kLeading from. the exhaust chamber 43 1s a pipe 46.

The pressure regulating chamber 16, the

stator casing 24l and the exhaust chamber 43 are held together by bolts 47. l J

The device as described is adapted to be operated by steam, however,- in Figs. 7 and 8 a slightmodilication is illustrated showing the same device adapted to be operated by water. The construction oft the device is practically the same except that the shape of various parts are modiiied to accommodate theuse of water as a driving fluid.

In Fig. 7, the motor is shown mounted on a concrete base and adapted to be .operated byk a vertical shaft instead of the horiw Zontal shaft. 'The operation of the device,

however, is identical, and therefore the devscription of the first typewill suflice.

The operation ofthesdevice is as follows: A driving huidig introduced-'through the supply 4pipe 14within the pressure regulatingichamber 16.` The amount admitted 1s regulated'bythe valve `15 which is ycontrolled by fmeans of the lever-34 attached f' at its louter end to -an adjustable tension bar 17. The lever is in turn operated bythe pushV rod 21 whichlis the stem of said piston mounted in the cy1inder19 which is connected to the top of thepressure regulating chamber. Fluid acting on the piston has a tendency to lclose the valve,`fwhereasthe action of the spring 18 ot the tension bar lhas a tendency to V,keep the *valve open.

Therefore when the pressure becomes too great in the pressure regulating chamber, the piston will be forced upwardly to cause the valve to be partially'or totallyfclosed k'until the pressure in the chamber is reduced when the pistonwill'lowe'r allowing the valve toopen.- In this way, by adjustment ofthe nut 35 on the piston rod any desired pressure may be maintained'in the pressure regulating chamber. i

The driving fluid passes throughI theports 31 in the side ofthe pressure chamber and ports 32 of the rotor casing. By movement of the throttle, the amount of driving fluid admitted to the rotoris regulated. The steam or other driving, fluid is admitted through the-se ports when they are in alignment, with the kpockets 33 in the rotor 22. Theports are-soarrang'ed that steam can casing.

abutments 42 and the action of the steam in the recesses A3S will push the sliding pistons into contact'withth'e perimeter of the stator The action oi the steam in the expansion chambers 41 will rotate the rotor,

and the slidingvpistons will ride over the inclined abutments. The intake ports are so arranged thatthe same will be out oit from the pockets 33 before the steam is allowed to escape through the exhaust ports 45, to the exhaust chamber 43. y

The inclined abutments force pistons back into the slots 3G, `into position 'for the operation tobe repeated and to constitute a ulcrum for .thepistons 37. It will be noted that the differentparts are so arranged that no two pistons are in the same reiative position to the fulcrum at one time.

The application of the Verniery like principle' in fixing the ratio ofthe number of fulcrums or sli ding inclined abutments to the number of sliding vanes or pistons, and

v at `the samejtimc ilnalring them harmonize kthe-same relative position,` to any of the remaining pistons to theffulcrums. Inother the sliding .words while 4one sliding piston is in an inl ,f active orpneutral positiomallbut one of the remaining ones are being kdriven on by the pushing of the steam 'or other power element, thereby multiplying or increasing the power over a one fulcrum engine by as many times minus one aslthe -numberof fulcrums employed in the new formof motor. Such must always be the result because three hundred and sixty or the sum of the degrees in acornplete lcircle is designedly made to be the leastl common multiple of the number of degrees'subtending respectively, the. arcs of twoadja'cent fulcrums and two adjacent sliding pistons. e

The Vadvantage of this basic feature is obviousjand the 4design -admits of employing as many oras few fulc'rums as may be required to vdevelopjpower required in the performance.Av of ,the work for which any particular motor, is built. n

An advantage of this type of motor over both the-steam and water turbine is this,

namely: that the turbine can notcarry its load4 until after first ,gaining great speed, which-'speed it must hold land at the yexpense ofan immense quantity of driving power; whereas my new motor may take up `and carry the full load from the very start, and that, whether running very slow orat `'full enter these pockets `whenthe sliding vanes l'Ihekspeed of the 'motor is regulated by the rotary valve or throttle 27. This motor can be adapted to be operated by Water or compressed air, as vvell as steam by modifying the shape of the various parts as shown in Figs. 7 and 8 of the drawings.

It is to be understood that the form of my invention herewith shown and described is to be taken as the preferred embodiment of the same, and that various changes in the shape, sizel and. arrangement of parts may be resorted to Without departing from the spirit of my invention or the scope of the subjoined claims.

I-Iaving thus described my invention what I claim is:

l. A rotary motor comprising a stator, including an outer annular Wall having a plurality of equidistantly spaced expansion chambers each terminating` in an abruptly enlarged portion, inclined abntments formed on the inner surface of the Wall at said chamber and disk-shaped side Walls having inlet and outlet ports formed therein arranged in annular formation, a rotor mounted Within the stator, a plurality of sliding vanes carried by the rotor, a steam chamber carried by one side Wall and housing said ports, means for supplying steam to said chamber, a rotary valve disposed between the steam chamber and the stator having a plurality of openings therein for controlling the flow of steam through said ports, means for operating said valve, an exhaust chamber carried by the other side Wall of the stator and housing said outlet ports, and an outlet pipe carried by said chamber. Y

2. A rotary engine comprising a stator including side Walls, having inlet and outlet ports formed therein respectively and arranged in annular formation, and an outer annular Wall having a plurality of equidisytantly spaced expansion chambers, each terminating in an abruptly enlarged portien, inclined abutments arranged at the enlarged terminals of the expansion chambers, a rotor disposed in said stator having pockets formed in one of the side faces arranged to communicate with the inlet ports, and radially extending slots communicating with the pockets, vanes slidably mounted Within the said slots having Ways therein communicating with said pockets for permitting the flow of the operating fluid from the pockets into the expansion chambers, and inlet and outlet chambers carried by the side Walls of the stator and housing said inlet and outlet ports.

In testimony whereof I affix my signature. i
